It appears that I am using version 2.3.0.1 of TAdvMemo.
Click and dragging or holding shift and using the arrow keys to highlight all or a portion of the line the text causes the highlighted portion to become visible. Also using shift+end to highlight the entire line does not cause the highlighted text to be visible, but holding shift and pressing the arrow keys to deselect text causes the deselected characters to be printed and selected characters to be hidden.
To recreate, start with a new VCL Forms Application. Add only a TAdvMemo. In the constructor add the following:
__fastcall TForm3::TForm3(TComponent* Owner)
: TForm(Owner)
